Mena kei te hiahia koe ki te mōhio atu ki ētahi atu kōrero, pēnei i te whakatau utu, ngā hua, ngā otinga, me ētahi atu, prīhiwhakapā mai ki a mātou i runga ipurangi.
He toa hokohoko a Tianjin Sanon Steel Pipe Co., Ltd. Kei te Tāone o Cangzhou, Porowini o Hebei tō mātou wheketere. Ko ā mātou puna matua o ngā taonga kongā paipa kōhua, ā, ko ngā rauemi e whakaatu ana i tēnei koASTM A335 P5/P11/P91/P92,ASME SA-106/SA-106MGR.B,GB/T 3087-200810#/20#. Ko ngā rauemi matua mō ngā paipa paipa koAPI 5L,API 5CT, ngā rauemi matua mō ngā paipa pakaru hinuGB/T 9948he 15MoG/12CrMoVGKo te GB/T 6479-2013 e tohu ana i ngā rauemi 10#/20#, ngā ngongo whakawhiti wera SA179/SA210/SA192, me ētahi atu.

I roto i te mara o ngā paipa maitai waro, ko te ASTM A500 Grade C meASTM A106 Tau Ce rua ngā paerewa rauemi e whakahuatia pinepinetia ana. Ahakoa he maitai waro e rua, ā, he rite tonu te tohu "Kōeke C", he rerekē rawa atu rāua i roto i te rapunga whakaaro hoahoa, ngā tukanga hanga, me ngā horopaki tono. Ka whakaratohia e tēnei tuhinga he whakatairite taipitopito mai i ngā ine maha, tae atu ki ngā whakamāramatanga paerewa, te hanganga matū, ngā āhuatanga miihini, ngā whakatakotoranga ine, me ngā taiao e tika ana.
1. Whakamāramatanga Paerewa me ngā Whakamahinga Matua
ASTM A500 – taitara katoaWhakatakotoranga Paerewa mō ngā Ngongo Hanganga Rino Waro kua Whakarewahia Matao me te Kore-Tuitui i roto i ngā Porowhita me ngā ĀhuaE ai ki te ingoa, he paerewa ngongo hanganga tēnei, e tika ana mō ngā ngongo hanganga maitai waro kua whakarewahia matao me te kore hononga, porowhita, tapawhā, me te āhua motuhake. E whakamahia ana i roto i ngā anga hanga, piriti, me ētahi atu hanganga mō ngā hononga whakarewa, whakakīkī, whakapūmau rānei. E kapi ana te ASTM A500 i ngā taumata A, B, C, me te D, ko te Taumata C te taumata kaha teitei rawa e whakamahia whānuitia ana.
ASTM A106 – taitara katoaWhakatakotoranga Paerewa mō te Paipa Rino Waro Korekore mō te Ratonga Pāmahana TeiteiHe paerewa paipa pēhanga pāmahana teitei tēnei, e tika ana mō ngā paipa maitai waro kore hononga anake, i hangaia mō te kawe i te mamaoa, ngā wai, me ētahi atu pāpāho i raro i ngā āhuatanga pāmahana teitei me te pēhanga teitei. Ka kapi te ASTM A106 i ngā taumata A, B, me te C, ko te Taumata C te taumata kaha teitei rawa atu.
Te rerekētanga matua kotahi-rerekētanga: Ko te A500 Grade C he ngongo hanganga e pikau ana i te kawenga; ko te A106 Grade C he paipa pēhanga mō te kawe wai.
2. Tukanga Hanga me ngā Āhua Hua
He rerekē rawa ngā paerewa e rua i roto i te tikanga hanga me ngā āhua e wātea ana:
| Āhuatanga | ASTM A500 Tau C | ASTM A106 Tau C |
|---|---|---|
| Te Hanga | He mea whakarewa matao-hanga (ERW) he mea tuitui rānei | Kore-tuitui anake (tuhi wera-oti, tuhi matao rānei) |
| Ngā Āhua | Ngā wāhanga porowhita, tapawhā, tapawhā hāngai, me ngā wāhanga motuhake | Porowhita anake |
| Tikanga tono | Mā te diameter o waho × te matotoru o te pakitara (OD × WT) | Mā te rahi paipa ingoa (NPS) me te tau o te hōtaka |
Ko te kaha o A500 ki te kapi i ngā wāhanga tapawhā, tapawhā hāngai, me ētahi atu wāhanga kore-porowhita he whakaata tika i tōna whānuitanga – "i roto i ngā Porowhita me ngā Āhua" – kāore nei i a A106.
3. Awhe Ahu
ASTM A500 Tau C: E pā ana ki ngā ngongo kāore e neke ake i te 2235 mm (88 inihi) te taha, ā, kāore e neke ake i te 25.4 mm (1 inihi) te matotoru o te pakitara. Ka taea e ngā rahi ngongo tapawhā noa te eke ki te 22 inihi × 22 inihi. Te ātete ki te matotoru o te pakitara: kaua te matotoru pakitara iti rawa e inehia e iti iho i te 90% o te matotoru pakitara kua tohua.
ASTM A106 Tau C: E pā ana ki ngā paipa kore hononga me ngā rahi paipa ingoa NPS ⅛ ki NPS 48 (DN 6 ki DN 1200), me ngā matotoru pakitara e ai ki te ASME B36.10M (ngā kaupapa 10 ki 160, XXH, me ētahi atu). Te ātete ki te matotoru pakitara: kaua te matotoru pakitara iti rawa e iti iho i te 87.5% o te matotoru pakitara kua tohua.
4. Whakataurite i te Hanganga Matū
Ko ngā rerekētanga o te hanganga matū e whakaata ana i ngā whakaritenga mahi motuhake. Ko te A106 Grade C e hiahia ana ki te silicon (Si ≥ 0.10%) hei whakapai ake i te ātete wera me te ātete waikura, engari ko te A500 Grade C kāore e hiahiatia he silicon. Ka whakatakotohia hoki e te A106 he rohe pakari ake ki ngā poke kino pēnei i te phosphorus me te whanariki hei whakarite i te pono i raro i te ratonga pāmahana teitei me te pēhanga teitei.
| Huānga (mōrahi, %) | ASTM A500 Tau C | ASTM A106 Tau C |
|---|---|---|
| Waro (C) | 0.27 (tātari hua) | 0.35 |
| Manganēhi (Mn) | 1.40 (tātari hua) | 0.29 – 1.06 |
| Whēkau (P) | 0.045 (tātari hua) | 0.035 |
| Whānariki (S) | 0.045 (tātari hua) | 0.035 |
| Hiraka (Si) | Kāore e hiahiatia | ≥ 0.10 |
He mea nui kia mōhiotia, ko te nui o te waro i roto i te A500 Grade C (0.27%) he iti iho i tērā o te A106 Grade C (0.35%), ā, ka pai ake te āheinga whakarewa o te A500 Grade C, ā, ka whakaiti i te tūponotanga o te ngatata i te wā whakarewa.
5. Te Whakataurite i ngā Āhuatanga Mīhini
He rerekē ngā whāinga kaha: He nui ake te kaha tuku o te A500 Grade C, he pai ake mō te ātete i te whakarerekētanga tuturu o ngā hanganga, ko te A106 Grade C ia he kaha kume teitei ake, e whakaata ana i tōna kaha ki te ātete i te pēhanga o roto me te ārai i ngā pakarutanga pahū.
| Taonga | ASTM A500 Tau C | ASTM A106 Tau C |
|---|---|---|
| Kaha Hua Iti rawa | 345 MPa (50,000 psi) | 275 MPa (40,000 psi) |
| Kaha Kume Iti rawa | 425 MPa (62,000 psi) | 485 MPa (70,000 psi) |
| Te Whakaroa Iti rawa | 21% | He teitei ake te nuinga, he pai mō te piko, te whana, me ētahi atu. |
He pai ake te ngāwari o te A106 Grade C, he pai mō te piko, te whakakoi, me ētahi atu mahi hanga paipa. I tētahi atu taha, ka eke te kaha teitei o te A500 Grade C mā te whakapakeke i te wā hanga matao.
6. Ngā Taiao me ngā Waehere Hangarau e Pā Ana
E whakamahia ana ngā paerewa e rua i roto i ngā taiao rerekē, ā, e whai ana i ngā waehere hoahoa rerekē:
| Āhuatanga | ASTM A500 Tau C | ASTM A106 Tau C |
|---|---|---|
| Awhe pāmahana | Ngā hanganga pūmau ā-pāmahana me te pāmahana iti; kāore he whakaritenga mahi pāmahana teitei | I hangaia mō te mahi pāmahana teitei, tae atu ki te 427°C me runga ake |
| Ngā tono noa | Ngā anga hanga, ngā pou piriti, ngā tautoko mīhini, ngā hanganga pourewa | Ngā whare whakapai hinu, ngā tipu hiko, ngā paipa mamaoa pāmahana-teitei/pēhanga-teitei me ngā paipa tukatuka mō ngā pūwero |
| Ngā waehere hoahoa | Ngā waehere hanganga AISC (American Institute of Steel Construction) | ASME B31.1 (Paipa Hiko), B31.3 (Paipa Tukanga), me ētahi atu waehere paipa pēhanga |
7. Ngā Aratohu Kōwhiringa
I roto i te whiriwhiri rauemi hangarau mahi, ka taea te whakamahi i ngā mātāpono e whai ake nei:
- Āhua tuatahi: Mena e hiahiatia ana he ngongo tapawhā, he ngongo tapawhā, he ngongo āhua motuhake rānei i roto i te tuhi, whiriwhiria te ASTM A500 Tau C – Kāore rawa a A106 e whakaputa i ēnei āhua.
- Mō ngā ngongo porowhita, whakaarohia te whakamahinga: Mena he pou hanganga, he tautoko whakarara, he mema whariki rānei kua pāngia e ngā kawenga hau, ngā kawenga mate, ētahi atu kaha o waho rānei → whiriwhiria te ASTM A500 Taumata C. Mena he paipa tukatuka e hono ana i ngā taputapu, e kawe ana i te mamaoa, i ngā wai warowaihā rānei i raro i te pēhanga me te pāmahana teitei o roto → whiriwhiria te ASTM A106 Taumata C.
- Pāmahana: Mō ngā wāhanga hanganga pāmahana taiao, tīpakohia te A500 Taumata C; mō ngā pūnaha paipa ka mahi tonu i ngā pāmahana teitei (≥350°C), tīpakohia te A106 Taumata C.
Hei whakarāpopototanga: mō te kawe kawenga hanganga, whakamahia te A500 Taumata C; mō te kawe wai pāmahana teitei, whakamahia te A106 Taumata C. Kāore e taea te whakawhiti i ngā mea e rua i roto i te hangarau.
